There are probably on a few people on the planet who might get the reference to that joke. That's fine. It was something done for one day, in place of the usual green gizmo. And I don't expect people to know what the green gizmo was about either.
About 20 years ago, I was at Boy Scout camp and they decided to have DeMoulas Day. Maybe we got some sort of contribution from the supermarket chain of the same name. I don't know. I also don't know why I kept a flier for it. Nor the partially filled out blue card for a merit badge.
I also found the instructions to my first bass amp, which I still own. I didn't throw them away this time, but just filed them with the other instructional booklets I have in my file cabinet.
(And if you really want to know what the green gizmo was about, I'll tell you. In camp, every day before lunch, somebody on the staff would secrety slip a "green gizmo" into the pocket of somebody. It was just some green object; I never saw it up close. Then during lunch announcements the staff would ask "Whhhhho's got, the GREEEEN GIZMO!?!" People would check their pockets. The person who had it would win a prize. On DeMoulas Day, they just changed it to "the red DeMoulas", which was probably just the plastic cap to a milk jug. There, now wasn't that a compeltely useless story?)
